Statement coverage and unreachable code

TaskIn 1this section we will show unreachable errors using the C language. Unreachable statements are statements that will not be executed during the program execution.

1. Return Statement Before Print Statement

#include <stdio.h>
int main() 
{
    printf("text_1"); 
    return 0; 
    printf("text_2");
}

2.  Infinite loop before statements

#include <stdio.h>
int main() 
{
  int x = 5;
  for (;;) 
  {
    if (x == 5)
    {
      break;
      printf("Hello World"); 
    } 
  }
  return 0;
}

3. Statements after continue statements

#include <stdio.h>
int main() 
{
  for (int i = 0; i < 10; i++)
  {
    continue;
    printf("Hello World");
  }
  return 0;
}

4. False conditions in if statements

#include <stdio.h>
int main()
{
  double X = 1.55;
  if (X > 5) 
  {
    X++;
  }
  return 0;
}
